We are all connected; To each other, biologically. To the earth, chemically. To the rest of the universe atomically.

Dinosaurs are extinct today because they lacked opposable thumbs and the brainpower to build a space program.

We are all connected; To each other, biologically. To the earth, chemically. To the rest of the universe atomically.
